n'nrvmc SHIELD.

Original No. 1,643,508, dated September 27, 1927, Serial No. 50,164, filed August 14, 1935. Application for reissue filed October 19, 1927. Serial No. 227,338.

This invention relates to eye shields for motorists and it has particular reference to that type of shield in the form of spectacles, goggles or eyeglasses employed while driv- 5 mg, the glasses of which are provided with sections of difi'erent .colors, to function as shields for the eyes at different. angles from which the objectlo'nable glare may come, and the rimaryobject of the invention comprehen s a shield having such glasses but which are constructed in such a manner as to afford in cases of night driving especially, a view of the entire road for a limited distance,

a view of halfthetroad for a limited disermittin a view of the road only through t clie shade portions of the glass, to shield the eyes from distance approach of lights.

The invention further contemplates the provision ofdise shields, by the utilization of which at no time is the vision entirely obliterated by the position of the discs, in an efiort to shield the eyes from glaring headlights orrays of the sun, and further, discs which may be rotated to effect neutral1-- zation of glaring lights at angles from which they come. 7 With the foregoing objects and advantages in view, the invention has particular reference to the novel construction of the discs, by which these and other objects are attained, such construction will be manitested and made clear in the course of the following detail description and illustrated 85 in the appended drawings, wherein:

Figure 1 represents a spectacle frame of the usual type, showing discs constructed in accordance with the present invention, rotated to a point of advantage for usual night Q driving.

Figure 2 is a similar view illustrating the manner in which the discs are disposed to shield the eyes in advancing toward the sun.

In employing similar characters of reference in proceeding. the Figure 1 illustrates ,the ordinary spectacle frame having rims 1, straps 2' and bridge 3, and in which are shown discs 4, constructed according to thepresent invention.

It is a known fact that various forms typesof eye shields and driving shields have been contemplated in which sectional lenses have been incorporated, consisting of glass and an effort to lessen the' danger incident to night (lIlVll'lg. The present invention howand like material of different shades, with ever, affords discs in substitution of lenses,

constructed preferably of non-breakable, translucent material or its equivalent, in which vislonal apertures are arranged of preferably apostrophic shape, as illustrated,

forming a protuberance 5, converging to a I ances 5 over the upper left side of the eyes.

As in most cases, driving to the right is adhered to, and in this regard; the protuberances 5 effectively shield the eyes from the blinding glare of an approaching light on the left, simultaneously permitting the wearer to discern the right side of the road with unobstructed vision, as thesemi-trans- -parency of the discs 4 neutralizes the objectionable glare, while the lobes of the a rtures a. afiord a greater view of the ma to a predetermined point distant from the wearer thereof. No rotation of the discs 4 is required, except to adjust the protuberances to change the vision to accord with the angle from glare may come.

Referring to Figure 2, the discs are positioned toexpedite driving toward the sun. In this instance. the protuberances 5 are disposed directly above the eye, to permit the which the objectionable line of vision to pass directly therebeneath,

whereby to shade' the eyes from the glaring rays of the sun, on a line with the horizon,

simultaneously permitting unobstructed view of the road and either side thereof.

It is well established that a divisional line disposed diametricallv of the glass, whether it be centrallv situated or otherwise. to aflord colored shades, is annoying to the vision. and prohibits a clear unobstructed view of the road. The present inf vention provides discs which are arranged .100 to shield only that part of the vision suhiected to the obiectionable ravs of light. in

such a manner as to avoid the necessitv of mensions than the translucent portion, proof the invention as set forth due to the semi-transparency of the shad portion.

' I The upper marginal edges defined by the opemngs a are comprised of a central convex part flanked by concave side parts, the edgesbeing int ing a sing e line to the eye, which line is of gradual curvature so as to be devoid of abrupt or harsh portions, thereby to intercept vision with a minimum strain or stress on the eye.

The invention has been described as embodying discs wherein the transparency of the central portion thereof is obtained through an a rture, but it should be herein understood at tr arent glass or its equivalent may be substituted for these aperhires, also the defcribed shape thereof may be shghtl altered to attain similar results, without eparting from the spirit or intent concave intermediate portion and convex end I, and continuous and present- 1n the follow I portions, one of which latter is larger than the other and disposed toone side of a vertical line drawn diametrically through the discs, whereb said discs have enlarged porto-one' side of said line and tions dispos the enlarged por- 'end portions, one of which latter is larger than the other and disposed to one side of a vertical line drawn diametrically through the discs, whereby said discs have enlarged portions ditposed to one side of'sa'id' line and at the'opposite ends of the enlarged portions of the openings.

3. A driving shield, comprising a. body of semi-transparent material, said body having a curved lower edge which is formed to have a convex intermediate portion and concave end portions, one of which latter is larger than the other, the convex intermediate portion being disposed to one side of a vertical line intercepting the center of the field of vision.

In testimony whereof I aflix my signature.
